BORING WRAPPING MACHINE Application filed November 2a, 1928. Serial no. 322,410.

This invention has for its object to provide a wrapping machine for wrapping articles varying in size, that is to say to provide a machine of this character which may be adjusted to adapt it to wrap an article of one size, may then be adjusted to wrap an article of another size, and so on. In the instant case, the machine is designed and adapted to wrap butter prints or' bricks or.

articles of similar shape and dimensions but may be changed and varied in some structural details to adapt it to wrapping articles of 'sizesand shapes differing from those of conventional butter prints or bricks.

This machine, as illustrated in the accompanying drawings, comprises a series of associated mechanisms, each of which accomplishes certain definite objects which will be best understood and appreciated if stated in connection with each of said mechanisms as described and are, therefore, set forth accordingly in the following pages.

In the accompanyin drawings illustrating a machine embodying the invention:

Fig. 1 is aside elevation of a butter print wrapping machine constructed in accordance with the invention.

Fig. 2 is a fragmentary side elevation of the same looking at the side of the machine view of the means employed for completing opposite that shown in Fig. 1.

Figs. 3 and 3 together constitute an en larged vertical longitudinal section of the machine on a plane just inside of the side frame of the same shown in Fig. 1.

Figs. 4 and 4 together constitute an enlarged vertical transverse section of the machine on the line 44 of Figs. 3 and 3.

Fig. 5 is a fragmentary detail vertical section on a plane substantially midway between the side frames. 1 1

Figs. 6 and 7 are fragmentary detail sections similar to Fig. 5 showing parts of the machine in different positions.

Fig. 8 is a further enlarged fragmentary detail vertical longitudinal section of a plane inwardly of but adjacent to the plane of the section shown in Figs. 3 and 3*.

Fig. 9 is a fragmentary plan section of the machine on the line 99 of Fig. 1.

Fig. 10 is a fragmentary plan section on i the line 1010 of v Fig. 11 is a. sectional view similar to Fig. 10 showmg the machine adjusted and equipped to wrap larger articlesitha'n could.

be wrapped by the same as shown in Fig. 10.

Figs. 12 and 13 are detail sectional views.

on the lines 1%12 and 13-13 res ectivelf of Fig.5. p

Fig. 14 is a plan section of the primary feed mechanlsm of the machine on-the line 14-44 of Fig. 1. 1

Fig. 15 is a fragmentary vertical longitudinal section on the line 15-15 of Fig.- 1 4. Fig. 16 is a fra mentary detail sectionon the line 16-16 of Fig. 14;

Fig. 17 is a central longitudinal section of one of the paper feed rolls employed.

Figs. 18 and 19 are detail sectional views on the lines 18-;18 and 19-49, respectively,

of Fig. 2.

Figs. 20 and 21 are fragmentary detail perspective views showing the cutting and a part of the primary feed mechanism of the machine.

Fig. 22 is a fragmentary detail perspective view of-.a partially wrapped arcel trans' ferring mechanism of the mac ine.

Fig. 23 is a fragmentary detail perspective the wrapping of the parcel.

Figs. 24 to 27 inclusive illustrate the successive steps performed by the machine in foldingthe ends of the paper wrapping of a parcel by the means-shown in Fig.23.

Fig. 30 is a sectional view on the line of Fig. 29.

Primary feed mechanism The machine, as illustrated, being designed and intended to wrap butter bricks or bricks or prints of material of a similar nature,

fed into the same in the form of long slabs of said material or product, includes means for successively cutting from the end of the slab pieces of predeterminedlength, the cross-
